Welcome to the forum just make yourself at home.Hmmmm if a range hood got cooked it sounds to me like the smoker exhaust is plenty hot.....Is there not some way to just pipe the exhaust to the outside?

Is there any way you can push the smoke thru the exhaust with the fan rather than pull it Maybe a side draft that could push air into the exhaust away from the fire somewhere along the exhaust pipe therefore creating a pulling effect to help the exhaust No expert by any means - - just a thought
